Question about Mitsubishi Televison & Video

1 Answer

My HD 1080 looses convergerence. Adjusting the blue/red convergence or selecting factory setting doesn't do anything. The shape of the piture is kind of bowed and the lines and images are doubled giving a pink and a green line/image. Turning it off for a while can bring the picture back to normal for a short time. What's happening and is it an easy or expensive fix?

Hi,
It seems some lose / cold solder joints in convergence output circuit, specially at pins of convergence output chips, re-soldering of dry/ cold solder joints will fix the tv.
Let me know if you have additional question.
Thanks.

My mitsubishi medallion hd 1080 doesn't show content from component cable


Some of the older Mitsubishi with HD 1080 have only one component input for HD---it is marked on rear as DTV----also a model number may allow me to give another suggestion--Some of these sets (ws, wt, vs models) will on occasion lock out or disable the input/s.

Depending on model number most also have 3 hidden menus---one is the option menu----it allows with the Mitsubishi remote via a 4 digit number (by model number) to enter there and do a hard reset of the set----sets every setting back to factory original---seen it "cure" all kinds of odd problems from missing rear inputs, no sound, odd video issues---you name it.

Get me the model number and I will see if can find the code for yours--you can also try hooking first direct a 1080 blue ray or Dvd if you want to see if the input is active or not first.

I have a Philips 51PW9303 Rear Projection TV that had blue shadows around the sides of the screen and now has a green and red bowed line at bottom. Does I need a convergence board to solve this?


If the following doesn't work the tubes could be at the end of life:
Adjusting convergence:
Note: For best results, the Projection TV needs to be turned on for 15 minutes or longer before adjusting the picture tubes (convergence).

To adjust the convergence of the picture tubes:
  1. Press the 'MENU/SELECT' button on the remote.
  2. Press CURSOR RIGHT to enter the PICTURE menu.
  3. Use CURSOR DOWN and RIGHT to select and enter MANUAL CONVERGE.
  4. Press CURSOR RIGHT to select CONVERGE RED or press CURSOR RIGHT and DOWN to select CONVERGE BLUE.
  5. A crosshair will be shown on the screen. If there is any red or blue fringe around the crosshair, use CURSOR RIGHT, LEFT, UP, DOWN to try and merge the fringe colors with the crosshair.
  6. Press the 'MENU/SELECT' button to return to MANUAL CONVERGE menu.
  7. Press the 'EXIT' button to exit the menu.
If you are satisfied with the convergence you may stop now. Otherwise, you can continue and adjust the convergence more using mult ipoint convergence.
To Adjust multipoint convergence:
  1. Press the 'MENU/SELECT' button on the remote.
  2. Use CURSOR RIGHT to enter the PICTURE menu.
  3. Use CURSOR DOWN and RIGHT on the cursor ring to select and enter MANUAL CONVERGE.
  4. Press CURSOR RIGHT and DOWN on the cursor ring to select MULTIPOINT RED or MULTIPOINT BLUE.
  5. A grid of crosshairs will appear on the screen. If there is any red or blue fringe around any of them, press CURSOR RIGHT to enter NAVIGATE mode.
  6. Use CURSOR RIGHT, LEFT, UP, and DOWN to move to a crosshair that has a color outline.
  7. Press the 'EXIT' button to enter ADJUST mode.
  8. Use CURSOR RIGHT, LEFT, UP, and DOWN to merge the color with the crosshair.
  9. Press the 'STATUS/EXIT' button to return to NAVIGATE mode. Repeat as necessary.
  10. Press the 'MENU' button to return to the MANUAL CONVERGE menu.
  11. Press CURSOR DOWN until SAVE MULTIPOINT is selected.
  12. Press CURSOR RIGHT to save the multipoint settings.
  13. Press the 'EXIT' button to exit the menu.

When I set the Directv receiver box to the 1080i resolution mode, the picture on the TV is ghost mode with red and blue outlines around each figures. please help. When I set the receiver to the 480i...


This may sound strange but I have seen something like this once before in this model----In the customer menu select Convergence---DO THIS WITH NOTHING CONNECTED TO THE SET FOR SIGNAL-- IF THE multipoint convergence looks ok---I saw one of these sets where the problem was the box that was giving the set signal---easy to find out if you have them swap that box out for another---The TV does not know(convergence wise) whether you are 480 or 1080---yes, sometimes the set needs to be adjusted in each of these modes for Convergence---the set I saw the convergence was ok in 480 but out the window in 1080----he had another box in another room and when we swapped it the problem was gone.

Let me know if this helps you---in the 480 you can confirm this by hooking a DVD etc and if that looks good---suspect the box.

If you have any questions let me know--I am here to help.

Top left side of picture blur


You may have to clean the crt's and lenses and the mirror. Unit may need total convergence from the service menu. If image is blurred in only one area like the corner I would suggest NOT to adjust the electrical or mechanical focus.

53 inch rear projection tv bowed piture


THis set is notorus..bad to converge ...here at the shop seting the convergence takes up alot of my time... you may have to get a technician to converge in factory or service model.. this is something a non tech should not due "you can mess it up good" there may be a convergence amplifer board problem too. suggest getting a tech to chech it out. IF you can converge at all is a good sign that it might just be adjustment. average repair for this is 100 to 200

HDTV-AT&T UVERSE


First of all, is your blue "HD" light lit up on the front of your Uverse box?

If yes, then you're in HD

If No, you need to check your connections from Box to TV
1.Those Red-Blue-Green cables are for video only, they don't carry sound and shouldn't be connected to audio outs. Audio needs a seperate cable. Make sure your Red isn't on the audio out which is also red. Make sure your blue and green aren't switched with each other either. Check that at both ends.
2. Try an HDMI cable. It will carry audio and video together and it's one cord instead of 5.
3. What brand/model of TV is it? Is it an older projection TV? The HD tuner might be shot. The individual color tubes commonly fail after a few years.
4. Are you selecting 720p or 1080i from your TV's menu or from the Uverse menu? You'll need to set it through the Uverse box, not the TV.
5.Follow -Menu -Settings -Aspect Ratio to change to 720 or 1080. This should start an autotest which will scramble your picture for about 5 seconds, then bring you back to a menu asking you to keep settings or revert back settings. If you never see that question pop up, then your TV isn't supporting the HD, and you settings will be rolled back automatically. If the question does pop up and you can read it, select "keep settings" and press OK. Your blue HD light should come on the front of the box now.

Convergence


Touch-up Convergence adjustments Enter the Digital Convergence Mode (DCM) by entering 0-6-2-5-9-7-(Status or Index) on the Remote control. The following menu will appear: Select an active channel or Aux Input. A signal must be applied to the set when performing convergence. If any Customer Adjustments need to be made, the Menu button can be used to toggle between the Customer Menu and DCM. The MPOSD ADJUST is used to center the Customer Convergence grid. A highlighted cross will appear along with the Convergence alignment grid. The highlighted cross should be centered onto the center of the Convergence grid. To perform a Touch Up Convergence, highlight SELECTION and press the right cursor button on the remote. The following menu will appear: Selections STORE, RESTORE FACTORY, and RESTORE DEFAULT are not shown after selecting SELECTION. Press the cursor down button on the Remote for these selections to appear. RESTORE FACTORY loads Convergence defaults from the Factory Loaded section of the Convergence Memory IC. RESTORE DEFAULT loads Convergence defaults from the sets software. To perform a Touch-up Convergence: 1. Enter the Convergence Mode and select RED TO GREEN or BLUE TO GREEN. Do not select GREEN (Green Geometry) without placing a Template over the screen. To perform Green Geometry, refer to the Complete in-depth Convergence. 2. Use the Cursor buttons on the Remote to Navigate from one adjustment point to another. Press the Status or Index button on the Remote to select ADJUST. Use the cursor buttons on the Remote to adjust the Red to Green or Blue to Green. Press the Status or Index button again to navigate to the next adjustment location. 3. After Convergence alignments are complete, press the Menu button on the Remote to return to the SELECTION menu. 4. Highlight the STORE selection and press the right cursor key on the Remote to save changes. 5. Use the GREEN TO RED or GREEN TO BLUE selections to perform convergence when the Green CRT has been replaced.
